Not worth worrying about too much I hope.
Lots of UTR were bought up to the high 2's followed by the cap. raise at 2.3c then others may have bought at what they considered a bottom near 2.1c. In my view it's just some portfolio rebalancing by a few. For what it's worth, I bought a few more than I wanted at 2.1c and offloaded a portion today to partly cover another opportunity.
Cheers
